HEATING APPARATUS.

Specification of Letters Patent.

Patented April 20, 19091 Application filed May 15, 1908. Serial No. 433,011.

g a full, clear, and exact description.

The invention relates to heating apparatus,

such as shown and described in the Letters Patent of the United States, No. 880,954, granted to us on March 3, 1908.

The object of the present invention is to provide a new and improved heating apparatus in which steam and hot water heating is combined in a very'simple and effective manner. 1 I

The invention consists of novel features and parts and combinations of the same which will be morefully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specrfication, in which similar characters of reference indicate corres onding parts in both views.

igure 1 is a sectional side elevation of the improvement; and Fig. 2 is an enlarged longitudinal central section of the fitting attached to the front radiator section.

The hot water radiator illustrated in Fig. 1 consists of a front or inlet section A, a rear or overflow section B and intermediate sections C interposed between the sections A and B. The u per end of the inlet section A is connectecl with a steam pipe D having a valve E and leading from the boiler or other source of steam supply. The lower end of the inlet section A is connected by an opening F with the lower end of the adjacent intermediate section C, and the intermediate sections 0 are connected with each other at their lower ends by openings F. The upper end of the inlet section A is connected by an opening G with the adjacent intermediate section C, and the several intermediate sections C are connected with one another at their upper ends by openings G, and the last intermediate section 0 is connected with the overflow section B by an openin G The bottoms of the several openings G and Gr are on the same level.

A plug H is arranged in the walls between the overflow section B and the rear intermediate section 0 near the lower ends thereof and in this plug H is secured one end of a return water pi e I extending through the openings F an F and connectingat its other end with a fitting J secured to the lower end of the inlet section A. The fitting J is provided with a discharge compartment 'J and a drainage compartment J and the said discharge compartment J is connected with a pipe K for returning the water of condensation to the boiler. In the bottom of the compartment J 2 is formed a drain opening J normally closed by a screw L screwin in the bottom of the fitting J and rendered t1ght by a suitable cap N, as indicated in Fig. 2.

The operation is as follows: The steam passes from the boiler or other supply by way of the valve D into the upper end of the first or inlet section A of the radiator and from this inlet section the steam can pass into the intermediate sections C and also into the overflow section B. The water of condensation effectually fills the inlet section A and the intermediate sections C up to the bottoms of the o enings G, G and any further water of conclbnsation overflows through the opening G into the overflow section B, from which the water can flow by way of the pipe I into the compartment J of the fitting J and by way of the pipe K back to the boiler.

B the arrangement described a uniform level of the water is had in the sections A and C of the radiator, while the section B is utilized as an overflow section from which the water of condensation can pass by way of the pipe I, so as to insure a rapid heating of the water contained in the sections A and 0. Thus by the arrangement described no sudden change of temperatureof the water in the radiator takes place, as the same water level in the radiator is maintained and the temperature of the water is raised evenly but very rapidly. The temperature is con trolled by the operator manipulating the valve E in the supply pipe D in the usual manner.

When it is desired to drain the sections A and C of water, it is only necessary for the o erator to partly unscrew the screw L, so

t at the water of condensation can flow from' are connected with one another at the hottom by the openings F, F, it is evident that all the water of condensation can be drained out of the said sections on unscrewing the screw L.

Having thus described our invention, we claim as new and desire to secure by Letters Patent:

1. A heating apparatus comprising a hot water radiator having a steam inlet section in communication with a steam supply, an overflow section for the water of condensa tion, intermediate sections interposed between the inlet section and the overflow section, all of said sections being provided with openings in their upper portions establishing communication between the sections, the bottoms of the several openings being on same level, the said inlet section and the in termediate sections having openin in their lower portions establishing communication between said sections, the openings being in horizontal alinoment with each other, and a return water pipe leading from the overflow section and extending through the said openings in the lower part of the other sections.

2. A heating apparatus comprising a hot water radiator having a steam inlet section, an overflow section for the water of condensation, intermediate sections communicating at their upper portions with the inlet section. and the overflow section, the said inlet section and the intermediate sections having openings in the lower portions establishing communication between the said sections, a return water pipe for carrying oil the water of condensation from the overflow section, and a fitting on the lower end of the said steam inlet section into which drains the said return water pipe.

3. A heating apparatus comprising a hot water radiator having an inlet section in communication. at its upper end with a steam supply, an overflow section, intermediate sections interposed between the said inlet section and the said overflow section, the said inlet section and the said intermediate sections being in communication with one another at the bottom, and the said inlet section, the intermediate sections and the overflow section being in communication with one another at the top, and a return water pipe leading from the bottom of the overflow section and extending through the openings connecting the intermediate sections and the inlet section with one another at the bottom.

i. A heating apparatus comprising a hot water radiator having an inlet section in.
